Review on ๐Ÿš— Dynomax Super Turbo 17734 Performance Exhaust Muffler by Roberto Evans

Revainrating 4 out of 5

Header, Offy Intake and 390 Holley REALLY spice up the old inline 6!

I have two of these installed on the F150 79 inline six. There were two manifolds in the manifold, hence two silencers. I tried Thrush glass bags but they were too noisy and harsh for this application. The Dynomax were loud enough to hear and quiet enough not to be intrusive.

Pros
  • Pretty impressive
Cons
  • Upgrade availability
